Dear lee,

Clean, safe water is vital for every day life. Water is essential for health, hygiene and the productivity of our community.The water treatment process may vary slightly at different locations, depending on the technology of the plant and the water it needs to process, but the basic principles are largely the same. This section describes standard water treatment processes. Sedimentation  is a physical water treatment process using gravity to remove suspendes solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation. Clarifiers are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation for the treatment of that sludge; filter first and then dry the sludge.

To remove the sludge from your sedimentation tank you should put at the bottom a valve that can be opened during the operation of maintenance of the treatment plan to evacuate the sludge. This sludge partially recycles to back of the clarifier and rest collected to sludge lagoon for dryness.  The sludge is distributed to basins with free capacity according to a loading plan. In this way, dewatering is optimised, thereby securing a high dry matter percentage, and prolonging the life of the sludge reed bed system. The loading rate of the system and basin level is computed on an ongoing basis.
